International audience. Two bacterial strains were isolated and identified using microbial culturomics and characterised according to the taxono-genomics strategy. The strictly anaerobic strain, Marseille-P3773(T), forms smooth and translucent colonies consisting of Gram-stain negative, non-motile and non-spore-forming rod-shaped cells. Strain Marseille-P3787(T) consists of Gram-stain positive, motile and spore-forming cells resulting in grey and translucent colonies. The phylogenetic analysis of the 16S rRNA gene of strains Marseille-P3773(T) and Marseille-P3787(T) revealed a 96.9% similarity level with Lachnotalea glycerini strain DLD10 and 97% identity with Paenibacillus uliginis strain N3/975, respectively. The genome of strain Marseille-P3773 is 4,260,534 bp long with a 40.3 mol% G + C content and includes 3879 predicted genes of which 3769 are protein-coding genes, 76 RNAs and 34 are pseudo-genes. Strain Marseille-P3787 had a genome size of 4,833,032 bp with a 47.9 mol% G + C and has 4481 predicted genes of which 4265 are protein-coding genes, 101 RNAs and 115 are pseudo-genes. According to the data collected on these strains and, more specifically to the genomic comparison, we suggest the creation of a new genus and species, Konateibacter massiliensis gen. nov., sp. nov. with strain Marseille-P3773(T) (=CSURP3773 and CCUG71331) as its type strain within the Lachnospiraceae family, as well as a new species, Paenibacillus faecalis sp. nov. with strain Marseille-P3787(T) (=CSURP3787 and CCUG71650) as its type strain within the Paenibacillus genus.
